The intestinal cavity is permeable to both sugars and waste. When intestinal cells are exposed to dialysis fluid, waste moves into the dialysis fluid along the concentration gradient. There is no net movement of sugar. The dialysis fluid is then removed from the body. When clean dialysis .

Please answer the following multiple choice question. Note that there might be more than one answer correct. 1. Living organisms share a number of characteristics. These unifying characteristics separate them from non-living things. For each of the following statements, check the statements that correctly distinguish living things from non-living things? 1. All living organisms are made up of one or more cells. 2. Only living organisms are complex. 3. All living organisms reproduce by passing on specific genetic information to future generations. 4. Only living organisms are capable of movement. 5. Only living organisms (populations) are capable of evolving. 6. Only living organisms require an input of energy to drive cellular activities. 7. Only living organisms produce heat as a byproduct of chemical reactions. 8. All living organisms are dependent on a constant supply of oxygen for survival. 9. Only living organisms respond to external stimuli. 10. All living organisms grow by increasing cell size and/or cell number. 2.

Place the following statements in the appropriate sequence showing the progression from an observation to a testable hypothesis. 1. You notice that the bread you left on the counter has more mold on it than do the rolls that you put in the refrigerator.You notice that the bread you left on the counter has more mold on it than do the rolls that you put in the refrigerator. 2. Does temperature affect the growth of mold or is the difference in mold growth related to differences between the bread and the rolls?Does temperature affect the growth of mold or is the difference in mold growth related to differences between the bread and the rolls? 3.

what regulations have been specifically implemented to monitor managerial accountants. Solution The purpose of management accounting is to support decision making by collecting, processing, and communicating information that helps management plan, control, and evaluate business processes and company strategy. According to business schools, the role of management accountant is to perform a series of tasks to ensure financial security of the company as well as help to drive overall business and management strategy. Traditionally the task of management accountant focused on the task of recording and reporting the management account information. With the change in technology, business environment, new production methods, global competition the role of management accountant has been shifted. Companies need to plan their operating activities within a particular budget. The role of management accountant now includes formulating strategic business plans and ensures corporate governance process. Management accountants are required to ensure adequate internal control system exists and also to [provide risk management. Technological advancement allows management accountant to track performance that is beyond historical cost based information. E- commerce has brought dramatic changes and role includes dealing with various ethical dilemmas. There are no specific regulations have been implemented to monitor managerial accountants however it the duty of managerial accountant to follow these rules and regulations 1 Establish and maintain financial policies and management information system 2 Provide high quality support 3 Prepare periodic financial statements 4 Formulating business strategies 5 Analyzing the financial implications of business decision 6 Liaising with other business managers and providing suggestions wherever required 7 Implementing corporate governance procedures, risk management and internal control. 8 Negotiating on major projects and loans 9 Interpreting and communicating financial data to other departments 10 They help in analyzing financial performance and adapt to changing circumstances.
